......the interesting thing was that the Roman Catholic monks and the Buddhist monks had no trouble understanding each other. Each of them was seeking the same experience and knew that the experience was incommunicable. The communication is only an effort to bring the hearer to the edge of the abyss; it is a signpost, not the thing itself. But the secular clergy reads the communication and gets stuck with the letter, and that's where you have the conflict.
